Display apparatus

A display apparatus includes a backlight assembly which provides a light and a display panel which receives the light provided from the backlight assembly to display an image. The backlight assembly includes a light source which generates the light, and a light guide plate. The light guide plate receives the light generated from the light source through an incident surface thereof as an incident light, and outputs the incident light through an exit surface thereof as an exit light. The light guide plate includes a first optical pattern and a second optical pattern. The first optical pattern is disposed corresponding to a first area of the exit surface and collects the incident light. The second optical pattern is disposed corresponding to a remaining second area of the exit surface excluding the first area, and collects the exit light.
